I recently got a phone call from a friend informing me that I had a new 4 cylinder engine and transmission. When I asked what it was he said he didn't know but it was cool. When I picked it up we went over it and found no maker name. Because it had long been stored in an old railroad depot it made me wonder about a rail car engine. It turns out it is a 1919 or 1920 Essex F head. This engine was used with a few changes from 1919 to 1923 in all Essex model As. It is a 179 ci, 55 hp, F head. It has no water pump, a full splash oil system one intake port and four exhaust ports. The first years had all Delco electrical components. In 1922 and 1923 the distributers were American Bosch. Also in '22, I think, maybe '21 in an attempt to improve fuel flow they moved the spark plugs from the intake side to the exhaust side of the head. They also lowered the compression. Essex was built by Hudson and was third in sales behind Chevrolet and Ford. In a 50 hour endurance run they went a little over 3,000 miles and averaged 60.7 mph. In 1922 Essex set cross country records in both directions in a bid for US Mail contracts. Four cars, two from New York driving west and two from San Francisco driving east made an average time of 4 days 21 hours 32 minutes. No doubt this was on the Lincoln Highway which was only 9 years old and over 3.000 miles long. The Lincoln highway was marked coast to coast but little if any of it was paved in 1922. In 1923 Essex won the Pike's Peak race 18 minutes 47.75 seconds. Essex won many other races. So with this solid race and speed history I'm excited and considering a vintage racer build. Dirt track, speedster, or a 3 springer lakes style. Any information, knowledge, parts sources, or thoughts are welcome.
